[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] like Figure 1 A high light utilization rate photovoltaic frame shown in the figure has a frame body, which includes a rectangular frame 1, an L-shaped frame 2 and a reinforcing rib 3, wherein the vertical side end of the L-shaped frame 2 is fixedly connected to the left corner end of the upper end surface of the rectangular frame 1, the reinforcing rib 3 is fixedly connected to the right bottom of the rectangular frame 1, is flush with the bottom edge of the rectangular frame 1 and extends to the right, and a slot 5 is formed between the L-shaped frame 2 and the upper end surface of the rectangular frame 1 to be inserted into the side of the photovoltaic component 4.

[0020] like Figure 2 , Figure 3 As shown, the horizontal upper plane of the L-shaped frame 2 includes a horizontal plane 2-1 on the left and an arcuate surface 2-2 inclined toward the lower right side on the right, and the arcuate surface 2-2 is provided with a reflective pattern 6 that can reflect light to the surface of the photovoltaic component 4, and the horizontal plane 2-1 is provided with anti-slip teeth 7 connected in sequence.

[0021] The cross section of the anti-slip tooth 7 is an isosceles right triangle. The reflective pattern 6 is composed of a plurality of saw teeth 8 inclined to the left connected in sequence. The head end of the reflective pattern 6 is connected to the end of the anti-slip tooth 7, and the end of the reflective pattern 6 ends at the lower right end of the arc surface 2-2.

[0022] The cross section of the sawtooth 8 can be triangular, semicircular or trapezoidal, and the height of the sawtooth 8 decreases from left to right on the arc surface 2-2, and the inclination angle of the sawtooth 8 decreases from left to right on the arc surface 2-2.
